The American space agency is hosting a competition in which a number of entrepreneurs will be showcasing a variety of interesting creations

A National Aeronautics Space
Administration competition will draw a number of international
scientists to the New Mexico desert for them to unveil a
number of different revolutionary projects. The overall goal of the NASA contest
is to build some form of a space elevator that would hopefully one day replace expensive rocket missions. Even though the idea of a
space elevator constructed out of a long enough cable to lift men and
goods into orbit seems a bit outlandish, the entrepreneurs
realistically believe it can be done.

University researchers, several
corporations and scientists from several countries will test their
devices to at the competition next month. Over $400,000 in cash
prizes will be made available to the winners to the contests.

The LiftPort Group is one company that
has openly stated its intentions of constructing a space elevator .
LiftPort announced last month that it has completed a second round of testing on a prototype space elevator platform that stretches over a
mile into the sky. The space elevator it hopes to construct would
span over 100,000 kilometers. The company will be represented at the
NASA challenge next month.

Even though a proper space base hasn't
been constructed on Mars, some experts are hypothesizing about the
ability of building a space elevator on the red planet. The 24
½-hour days and proper atmosphere makes it an ideal location
for a space elevator. Many scientists cited by the group agree that interested parties
should first build some sort of elevator off Earth before even
mentioning Mars.

Many people do. This particular metaphor is most often misused in South East Asia.

I'm sorry for you that you can't accept a correction, and that you start throwing around insults.

Someone who rejects information because it doesn't fit with their preconceptions, and gets "antsy" about it, has scientifically been proven to have, on average, an IQ which is significantly less than 100. (FACT)

Its funny how a metaphor that alludes to common household objects can only be applied to people!

Anyway, think about it a bit more. An idea doesn't exist on its own. An idea is not a "thing" in itself, but a proposition by another human being. If the idea is stupid, then the author of said idea is stupid. To criticise an idea, you are criticising the originator of that idea. Therefore, even by your own reasoning, this metaphor can be applied perfectly.
